Salvia plant named ‘Ignition Purple’

ABSTRACT

A new cultivar of  Salvia  named ‘Ignition Purple’ that is distinguishable by intense vibrant deep purple flowers which are borne on compact plants with mid-green glossy leaves, is disclosed.

Genus and species: Salvia×jamensis.

Variety denomination: ‘Ignition Purple’.

BACKGROUND

The present disclosure relates to a new and distinct cultivar of Salvia plant, also known as a sage, a perennial that is grown for use as an ornamental landscape and container plant. The new variety is known botanically as Salvia×jamensis and will be referred to hereinafter by the cultivar name ‘Ignition Purple’.

‘Ignition Purple’ originated and was selected from a large population of hybrid seedlings from a Salvia breeding program which was started in 2009. The breeding program was conducted in a greenhouse nursery in Elk, Calif. A controlled hybridization was carried out in 2012 using pollen collected en masse from many proprietary selections. The identity of the male parent is unknown. The collected pollen was applied to the flowers of Salvia×jamensis ‘Mes Azur’, also known as ‘Mesa Azure’ (U.S. Plant Pat. No. 21,097).

Seeds from this hybridization were sown and a single plant was selected in 2013 for its intense vibrant deep purple flowers which are borne on compact plants with mid-green glossy leaves, and was subsequently named ‘Ignition Purple’.

‘Ignition Purple’ was first asexually propagated in early spring of 2013 in a greenhouse at the inventors nursery in Elk, Calif. using softwood tip cuttings. ‘Ignition Purple’ is stable and reproduces true to type in successive generations of asexual reproduction.

SUMMARY

The following traits have been repeatedly observed and represent the distinguishing characteristics of ‘Ignition Purple’. ‘Ignition Purple’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, without however, any variance in genotype.

-   -   1. ‘Ignition Purple’ exhibits a compact well-branched upright         plant habit;     -   2. The flowers of ‘Ignition Purple’ are intense vibrant purple         in color; and     -   3. ‘Ignition Purple’ grows and flowers rapidly. Flowering plants         may be produced in 10 to 12 weeks from a cutting.

DESCRIPTION OF THE PHOTOGRAPHS

The accompanying color photographs illustrate the overall appearance of the new Salvia cultivar ‘Ignition Purple’ showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Photographs were taken in April, 2015 in Santa Barbara, Calif. of three-month old plants grown outdoors in quart containers, with one pinch after initial cutting establishment and without any chemical growth regulators. Colors in the photographs may differ from the color values cited in the detailed botanical description, which more accurately describes the actual colors of the new variety ‘Ignition Purple’.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘Ignition Purple’. Observations, measurements, values, and comparisons were collected in March and April, 2015 in Santa Barbara, Calif. from two to three-month old plants grown outdoors in full sun in quart sized containers in Elk, Calif., with one pinch after initial cutting establishment and without any chemical growth regulators. Plants were transferred to Santa Barbara, Calif. when in bud and observed through flowering. Color determinations were made in accordance with The 2007 Royal Horticultural Society Colour Chart from London England, except where general color terms of ordinary dictionary significance are used.

COMPARISON WITH PARENTAL LINES AND KNOWN VARIETY

‘Ignition Purple’ is distinguishable from the female parent, ‘Mes Azur’ as follows: ‘Ignition Purple’ bears smaller leaves which are also thicker, and grows with a denser plant habit with better branching. In addition, whereas the flowers of ‘Ignition Purple’ are an intense deep purple in color, the flowers of ‘Mes Azur’ are soft and muted purple in color.

‘Ignition Purple’ is similar to ‘Sunsaruoro’ (U.S. Plant Pat. No. 15,141), however the flowers of ‘Sunsaruoro’ are a light purple in color whereas the flowers of ‘Ignition Purple’ are a deep and vibrant purple in color. 

I claim:
 1. A new and distinct cultivar of Salvia plant named ‘Ignition Purple’ as described and illustrated herein.
